Description

POST /cliservice HTTP/1.1
Content-Type: application/x-thrift
Accept: application/x-thrift
User-Agent: Java/THttpClient/HC
Authorization: Basic YW5vbnltb3VzOmFub255bW91cw==
Content-Length: 71
Host: localhost:10007
Connection: Keep-Alive
Accept-Encoding: gzip,deflate
X-XSRF-HEADER: true

The Beeline client clearly sends out HTTP compression headers which are ignored by the HTTP service layer in HS2.

After patch, result looks like

HTTP/1.1 200 OK
Date: Tue, 01 Aug 2017 01:47:23 GMT
Content-Type: application/x-thrift
Vary: Accept-Encoding, User-Agent
Content-Encoding: gzip
Transfer-Encoding: chunked
Server: Jetty(9.3.8.v20160314)
